Twenty-nine people have been indicted in a sex trafficking ring in which Somali gangs in Minneapolis allegedly forced girls under age 14 into prostitution in Minnesota, Tennessee, Ohio and other unnamed places, according to an indictment unsealed Monday.

The indictment, unsealed in U.S. District Court in the Middle District of Tennessee, said one of the gangs' goals was recruiting females under age 18, including some under age 14, and forcing them into prostitution in exchange for cash, drugs or other items.

Gang members had been conspiring to recruit young girls for the sex ring since January 2000, the indictment said.

The indictment claims three Minneapolis-based gangs were involved -- The Somali Outlaws, the Somali Mafia and the Lady Outlaws -- and that the gangs are connected. It outlines several instances when young girls were told to engage in sex acts for money, marijuana or liquor.

In one case in 2005, a 13-year-old girl was taken from Minneapolis to Columbus, Ohio, and Nashville for sex.
